Well having lost a lot of weight that last couple years I have been going through riding jackets as I slim down. I have finally hit my target weight and was ready to buy a good all year jacket or at least 3 season excluding true winter temperatures. The Ignition 2 is a leather and textile combination jacket. It is leather in all the protection points where you would want it. Arms, shoulders, back pieces and all the straps etc. High end zippers, Euro cut and styling. I rode today with it with some reservations about how well the mesh would actually flow. It is very tight knit mesh and I didn't expect it to do as well as some other jackets. Well I was wrong, I was very chilled honestly at mid 60s temp today wishing I had the thermal vest in. The jacket has two liners, the main liner is a breathable waterproof liner that supposedly still flows a lot of air so it can be worn in high temps without massive discomfort. The outer liner is the thermal vest that covers the area under the mesh to block the air and keep your core warm. I also have thermal top and pants that I can put on to augment this lining so I believe that I can ride down to freezing temperatures. I won't ride below the mid to upper 30s. I refuse to deal with the possibility of ice.
